cLosuRn f Application mea Augustlaieaa serirno. eeaieof This inventionrelates to closure devices, and more particularly to an improved form ofcap or closure for use on filler necks of automobile gasoline tanks,radiators, and the like.

An ob] ect of this invention is to provide an improved form of cap orclosure in which reenforcing means provided for the beaded and lnurledportions is housed within the closure body.

Another object of this invention is to provide an improved form of capor closure having a rigid backing member for supporting V those portionsof the closure body upon which y beading and knurling operations areperformed.

The invention may be further brieiiy summarized as consisting in certainnovel combinations and arrangements of parts hereinafter described andset out in the appended claims.

In the accompanying sheet of drawings forming apart of this application,

Fig. l is a bottom plan view of my closure;

Fig. 2 is a top plan View of myclosure with parts thereof broken away;

Fig. 3 is a sectionall View taken on line 3 3 of Fig. 2;

Fig. 4 is a side elevation with parts broken away, showing the closureapplied to a filler Deck; v

VFig. 5 is a detail showing the reenfo'rcing member in elevation; and

Fig. 6 is a detail showing one of the closure body parts in sectionalelevation.

Referring now in detail to the drawings, I show a closure having a bodyormed'of separate parts secured together by a beading operation, andprovided with a backing member which serves as an anvil for the beadingoperation. In illustrating the principle of my invention, I have shown aclosure which is adapted to be connected to a tubular member by means ofa bayonet joint, but, obviously, my invention is not limited in itsapplication to the particular form of closure illustrated but may beembodied in variou types of closures.

In the embodiment of my invention herein illustrated, the closure bodyis a hollow structure made up of an upper or cover part 10,

Va lower vorrslirt partl l1, and

'12,l all permanently.,securedatogether; The. i

skirtpart ll is provided with an annular f'angel which.isconcentridvvithand ,sur-V rounds an annulan'flange' 14e! formed` (nithe bottom partilQ.` ,I-These annular! anges are -reta-ined inengaging, concentric relation by Y deforrning,v orbeadingtthe. annularportion l@ of the cover` part garound the ,annularV fiange 13, asclearly showninFi'g. 3f.' The central? portion 'of th'ejbottom. par-t-'12 Yi`s` provided, `in/this instance, `vvith4 cup-shaped Vdepression 16uponwhich` is 'carried a locking ,member .17, and an extension member1.8. The locking memberfisf 4:provided 'Withiresilient fingers 19 whicheXtend-laterally through openingsl formed` .in the 'side` Wall;`of.-t;he'eX tensionm'ember 18 andrelea'sably engageginclined camsurfalces() fofrmed `on' the' tubular filler neclrQl-y PThe: I closure-isapplied to the y filler neck -b'y inserting theexte'nsion intdthe.filler neck; openingand-rotating thegcl-osure relative .to .the`neck',WhereupOi1]` the locking fingers engage andffollow. ,the inclinedcam surfaces, causing the .gasket-221. tobei compressed betweenthe bottom part ofthelclof sure andthe end yi-'the filler neck. Y

he closure body is formed of shell-like vsheet metal stampings which, aspreviously stated, are secured together by abeading operation, and topreventthese stampings VJfrom being distorted during the beadingoperation',

I prcvide a vrigid reenforcing or backing mem 'ber 23 Vwhich is receivedWithin the ring .formed by the annular flange 14, and after the partshave been assembled is wholly enclosed withinthe closure body. Thisrigid backing` or reenforcing member serves as an anvil so thatsufficient pressure can be applied to the body parts for beading theseparts toi,

gether without danger ofthe shell-like clo-v sure body structurecollapsing or being dis'-v torted. This backingv member also serves asan anvil for the knurling 24' which is applied i to the periphery ofthe'` cover part to facilitate grasping the closure for rotating thesame relative to the liller neck. f

The backing member. 23 is preferably formed as a solid metallicblock,sothat, in

addition to serving as an anvil for the beading and knurling operations,this member will also add Weight to the shell-like closure bodystructure. This additional Weight facilitates the handling ofthe closurein applying the same to the iller neck, and also has a tendency to)vprevent the :closure from Working oir-jarring loose from theiillerneek.. y Vhile I have shown and described the device of myinvention inra detailed manner, it 'should be' understood that I do notdesire to' limit myself to the precise' de'tails'sliovvn and described,but regard my'invention as including such changes `and modifications asdo not involve a departure from: the spiri/tof. my invention and thescope of the appended claimde.I s l Having thas described invention, I'dirimir I 1:.
